Die Erfindung bezieht sich auf Staubabsaugevorrichtungen mit einem Staubabscheider, bei dem vor dem eigentlichen Staubfilter noch eine besondere Entstäubungskammer vorgesehen ist. Die Erfindung wird darin gesehen, daß in die Entstäubungskammer ein Staubluftwirbelraum eingebaut ist, den, wie dies an sich bekannt ist, eine wagerechte Querwand von einem wirbelfreien SinkraumThe invention relates to dust extraction devices with a dust separator in which a special dedusting chamber is provided in front of the actual dust filter is. The invention is seen in the fact that a dust air swirl space in the dust removal chamber is installed, which, as is known per se, a horizontal transverse wall of an eddy-free sink chamber
ίο trennt. Wesentlich ist an diesem Staubluft wirbelraum, daß seine Ein- und Auslaßöffnungen mit schaufelartigen, der durchgesaugten Luft entgegengerichteten Prallflächen versehen sind. Auf diese Weise wird die Abscheidung der groben Staubteilchen aus der Luft begünstigt und erreicht, daß nur noch der feine Staub in das eigentliche Filter gelangt.ίο separates. What is essential about this dust air swirl room is that its inlet and outlet openings with shovel-like, the sucked through Air opposing baffles are provided. That way, the deposition the coarse dust particles from the air favors and achieves that only the fine Dust gets into the actual filter.

Das Gehäuse F dient zur Aufnahme der Entstäubungskammer und des eigentlichen Staubfilters. Durch den Saugstutzen e am Gehäuse F gelangt die staubhaltige Luft in einen geschlossenen Ringraum /, der sich zweckmäßig nach oben hin verjüngt. Aus diesem Raum f, der einen Teil der Entstäubungskammer K bildet, wird die· Luft durch Schlitze der Wand h in eine Kammer G gesaugt. Diese Kammer stellt den Staubluftwirbelraum dar; sie ist durch eine wagerechte Querwand H von einem Raum / getrennt, in welchem die groben Staubteile sich ablagern können.The housing F is used to accommodate the dust removal chamber and the actual dust filter. The dusty air passes through the suction nozzle e on the housing F into a closed annular space /, which appropriately tapers towards the top. From this space f, which forms part of the dust removal chamber K , the air is sucked into a chamber G through slots in the wall h. This chamber represents the dust air swirl space; it is separated by a horizontal transverse wall H from a room / in which the coarse dust particles can collect.
Es ist nun wesentlich, daß die Einlaßschlitze der Kammer G mit schaufelartigen Prall-40 It is now essential that the inlet slots of the chamber G with scoop-like baffles 40
flächen g versehen sind, die der durchgesaugten Luft entgegengerichtet sind und dem Luftstrom eine tangentiale kreisende Bewegung erteilen, wie dies an sich bekannt ist. Der kreisende Staub prallt gegen die Schau-" fein g und wird dadurch in seiner Bewegung gehemmt, bis er in den Sinkraum / gelangt. surfaces g are provided which are directed in the opposite direction to the air drawn through and give the air stream a tangential circular movement, as is known per se. The circling dust bounces against the display "fine g" and is thereby inhibited in its movement until it reaches the sink space /.
Die zweckmäßig gewölbte Deckelfläche / der Kammer G hat Auslaßschlitze, die in gleicher Weise mit Prallflächen /' versehen sind, so daß auch beim Auslaß Staub abgefangen Und in den Sinkraum. / niedergeleitet wird. Jedenfalls wird erreicht, daß nur die feineren Staubteilchen an den Prallflächen /' vorbei in den Raum K gelangen.The expediently curved cover surface / of the chamber G has outlet slots which are provided in the same way with baffles / 'so that dust is also caught at the outlet and into the sink space. / is diverted. In any case, it is achieved that only the finer dust particles get past the impact surfaces / 'into the space K.
Tn diesem Raum K befindet sich die eigentliche Filterkammer L, die durch Öffnungen k mit der Entstäubungskammer K in Verbindung steht. Die Filterkammer L ist zwischen den abnehmbaren Gewebefiltern j> mit Sägespänen / ο. dgl. gefüllt und steht durch die Stutzen M, N mit der Luftpumpe in Verbindung. The actual filter chamber L, which is connected to the dust removal chamber K through openings k, is located in this space K. The filter chamber L is between the removable fabric filters j> with sawdust / ο. Like. Filled and is through the connection M, N with the air pump in connection.
Als Deckel für das Gehäuse F bzw. die Kammer L dient eine Membran d, die durch einen mittels eines Reifens η festgeklemmten Metalldeckel 0 gegen Beschädigung geschützt werden kann. Eine Feder E, die sich mit dem einen Ende gegen den Deckel 0 der Kammer F stützt, sucht die Membran d ständig nach aufwärts zu ziehen.A membrane d serves as a cover for the housing F or the chamber L , and can be protected against damage by a metal cover 0 clamped in place by means of a tire η. A spring E, one end of which is supported against the cover 0 of the chamber F , constantly seeks to pull the membrane d upwards.
Wenn die Luftpumpe in Gang ist, wird die staubhaltige Luft bei e an- und zuerst in die Staubwirbelkammer G gesaugt, wo die Ab-Scheidung der groben Staubteilchen erfolgt. Aus der Kammer G gelangt die staubhaltigeWhen the air pump is running, the dusty air is drawn in at e and first sucked into the dust swirl chamber G, where the coarse dust particles are separated off. From the chamber G comes the dusty

Beim Ansaugen wird die Membran d, der Wirkung der Feder E entgegen, niedergezogen, wodurch das Hindurchsaugen der Luft durch die Filterschicht I befördert wird.Air into the filter space L and purified through the line M, N into the pump. When sucking in, the membrane d is pulled down, counter to the action of the spring E , as a result of which the air is sucked through the filter layer I is promoted.
